<p>Many states contain a number of double values. This function provides a means to get the memory address of a double value from state <em>state</em> located at position <em>index</em>. The first double value is returned for <em>index</em> = 0. If <em>index</em> is too large (does not point to any double values in the state), the return value is NULL. </p>
<dl class="note"><dt><b>Note:</b></dt><dd>This function does <b>not</b> map a state to an array of doubles. There may be components of a state that do not correspond to double values and they are 'invisible' to this function. Furthermore, this function is slow and is not intended for use in the implementation of planners. </dd></dl>
